A Structural Integrity and Maintenance Management (SIMM) audit is a formal structural inspection led by ECSA Professional Engineers. It maps active degradation and safety risks across processing corridors, supporting structures, and conveyors, helping plant operators comply with South African OHS statutory requirements.
Spoke Specialization: SIMM Auditing & Forensics
Plant Integrity & Auditing
Protecting major mining, heavy industrial, and commercial structures across South Africa with comprehensive, ECSA-certified forensic structural auditing.
ECSA-Certified Forensic Plant Inspections
Concrete deterioration, structural corrosion, and load-path shifts can compromise active plant spaces long before failure occurs. We analyze structural defects in clear, actionable business terms, matching raw observations with precise risk mitigation strategies.
Using high-accuracy non-destructive scanning and microscopic crack monitoring, our Pr.Eng inspectors diagnose the source of structural distress. We classify degradation parameters into ECSA-aligned risk levels to help plant managers optimize maintenance budgets and maintain strict OHS legal compliance without unnecessary operational downtime.
Our Auditing Method
The 4-Step Forensic Integrity Process
How we identify, isolate, and remediate structural degradation across high-load processing assets.
Step 01
Non-Destructive Scanning
We map internal reinforcement configurations and identify sub-surface voids without core drilling using high-frequency ground-penetrating radar.
Step 02
SIMM Risk Classification
We grade physical plant degradation on a standard severity index, separating structural risks from basic surface corrosion to optimize your maintenance spend.
Step 03
Dynamic Fatigue Modeling
We simulate plant operational loadings to predict structural fatigue, calculating remaining asset lifespan under real-world vibration profiles.
Step 04
Actionable Remediation Plans
We deliver comprehensive, ECSA-signed rehabilitation drawings. This includes direct carbon-fiber wrapping specifications and concrete patch procedures.
Forensic Engineering Capabilities
Dedicated testing and diagnostic disciplines engineered to extend active asset operational lifespans.
Concrete Defect Diagnostics
High-accuracy monitoring of active cracks, carbonation depth tracking, and mapping of internal rebar spalling caused by structural overloading.
SIMM Plant Auditing
Comprehensive, ECSA-registered visual and dimensional plant inspections mapped to South African OHS statutory requirements to preserve industrial licenses.
Rehabilitation Modeling
Advanced finite element analysis to simulate retrofitting repairs. This includes steel sleeve reinforcement additions and carbon-fiber composite layouts.
South African Case Study
Arnot Power Station Coal Silo Crack Forensics
Diagnosing microscopic movements in active high-load concrete silos
For a massive active concrete coal silo complex in Mpumalanga experiencing structural distress, IStructEng delivered the full forensic inspection and rehabilitation modeling scheme.
Our team mounted digital crack monitors and performed non-destructive rebound tests to model structural concrete strength. By analyzing actual concrete stress profiles, we proved the existing structures remained within safe operational limit states, helping the operator avoid a costly shut-down while planning a targeted, carbon-fiber wrap reinforcement procedure.
